The linear displacement sensor may be ametal membrane displacement sensor, a conductive plastic displacementsensor, a photoelectric displacement sensor, a magnetic sensitivedisplacement sensor, a metal uranium glass displacement sensor, awinding displacement sensor, or the like.

The sensor 200 may sense one trigger position in relative positions ofthe left body 110 and the right body 120. For example, when the sensor200 is a photoelectric sensor or a proximity sensor, the sensor 200 maybe triggered when the left body 110 and the right body 120 sliderelatively to the trigger position of the sensor 200.

The sensor 200 also may sense a plurality of trigger positions in therelative positions of the left body 110 and the right body 120. Forexample, in some embodiments, when there are multiple sensors 200, eachof which is a photoelectric sensor or a proximity sensor, acorresponding sensor 200 may be triggered as the left body 110 and theright body 120 slide relatively to the trigger position of the sensor200.

In some embodiments, the sensor 200 is a linear displacement sensor.When the linear displacement sensor senses that the left body 110 andthe right body 120 slide relatively to a preset position, the lineardisplacement sensor may send out a corresponding trigger signal.

It is noted that, the relative positions of the left body 110 and theright body 120 sensed by the sensor 200 may comprise a plurality oftrigger positions disposed spaced apart from each other that maycorrespond to a plurality of different control signals, respectively.

Referring to FIG. 1, the controller 300 may be connected incommunication with the sensor 200. When the sensor 200 senses a changein a relative position of the left body 110 and the right body 120, thesensor 200 may generate and send a position signal to the controller300. The controller 300 may send out a corresponding control signalaccording to the position signal.

The position signal may comprise coordinate information of a triggerposition. For example, a coordinate is zero when the left dockingportion 111 of the left body 110 and the right docking portion 121 ofthe right body 120 are fully docked. The coordinate is Lmax when theleft docking portion 111 of the left body 110 and the right dockingportion 121 of the right body 120 are fully pulled apart. Thecoordinates of a plurality of trigger positions in between may beinclude: the coordinate L1 of a first trigger position, the coordinateL2 of a second trigger position, the coordinate L3 of a third triggerposition, and the coordinate L4 of a fourth trigger position.

The controller 300, according to the coordinate information of a singletrigger position, may send out a trigger-control signal corresponding tothe trigger position. For example, when the left body 110 and the rightbody 120 slide relatively to the first trigger position, the controller300 may send out a corresponding control signal, i.e., the coordinate L1of the first trigger position corresponds to that control signal.

The controller 300, according to the coordinates of a plurality oftrigger positions, may send out a trigger-control signal correspondingto the plurality of trigger positions. For example, when the left body110 and the right body 120 slide from the first trigger position to thesecond trigger position, the controller 300 may send out a correspondingcontrol signal, i.e., the change from the coordinate L1 of the firsttrigger position to the coordinate L2 of the second trigger position maycorrespond to that control signal.

The controller 300, according to a displacement that the left body 110and the right body 120 slide relatively, may send out a trigger-controlsignal corresponding to the displacement. For example, when the leftbody 110 and the right body 120 slide from the first trigger position tothe second trigger position, the displacement is M1=L2−L1, and thecontroller 300 may send out a corresponding control signal, i.e., thedisplacement M1 that the left body 110 and the right body 120 sliderelatively may correspond to that control signal.

The controller 300 may control the remote controller itself according tothe position signal. For example, as shown in FIG. 1, in someembodiments, the remote controller 10 may further comprise a powerswitch 400 configured to control a power supply of the remote controller10. The power switch 400 may be connected in communication with thecontroller 300, and the controller 300 may control power-on andpower-off states of the power switch 400 according to the positionsignal.

The controller 300 may control a remotely controlled object according tothe position signal. For example, as shown in FIG. 1, in someembodiments, the remote controller 10 may further comprise a wirelesssignal transmitting device 500. The controller 300 may be connected incommunication with the wireless signal transmitting device 500 and maytransmit a control signal through the wireless transmitting device 500.

In some embodiments, the controller 300 may control the remotecontroller 10 itself and the remotely controlled object according to achange in the relative position of the left body 110 and the right body120. For example, in some embodiments, the remote controller 10 mayfurther comprise both the wireless signal transmitting device 500 andthe power switch 400 for controlling the power supply of the remotecontroller 10. The power switch 400 may be connected in communicationwith the controller 300. The controller 300 may be connected incommunication with the wireless signal transmitting device 500 and maytransmit a control signal through the wireless signal transmittingdevice 500. When the left body 110 and the right body 120 sliderelatively to the first trigger position, the controller 300 may controlthe power switch 400 to be in the power-on state to turn on the powersupply of the remote controller 10. When the left body 110 and the rightbody 120 continue to slide relatively to the second trigger position,the controller 300 may send out a control signal for controlling theremotely controlled object through the wireless signal transmittingdevice 500.

When the remotely controlled object of the remote controller 10 is aUAV, the control signal may comprise at least one of the following: asignal for controlling an extension-retraction state of theundercarriage of the UAV, a signal for controlling a deformation stateof the wing of the UAV, a signal for controlling an automatic return ofthe UAV, or a signal for controlling an automatic take-off of the UAV.

As compared with the conventional technologies, the above-describedremote controller 10 may at least have the following advantages:

When the interval between the ends of the left body 110and the right body 120 that are distal from each other needs to bedecreased, the left body 110 and the right body 120 may slide towardseach other.

(2) The left body 110 and the right body 120 of the above-describedremote controller 10 may slide relatively, and may serve as acontrolling switch structure of the remote controller 10, therebyexpanding the functions of the left body 110 and the right body 120 ofthe remote controller 10.

(3) The left docking portion 111 of the left body 110 and the rightdocking portion 121 of the right body 120 of the above-described remotecontroller 10 may slide synchronously, so as to allow the left body 110and the right body 120 to extend or retract synchronously relative to amiddle position therebetween, thus improving the operability of the leftbody 110 and the right body 120 as a controlling switch of the remotecontroller 10.

(4) The above-descried remote controller 10 may control itself or aremotely controlled object of the remote controller 10 through a changein the relative position of the left body 110 and the right body 120.

Based on the above-described remote controller 10, an embodiment of thepresent disclosure provides a method for controlling a UAV.

Referring to FIGS. 1, 2, 3, and 8, a method for controlling a UAV usingthe above-described remote controller 10 according to an embodiment ofthe present disclosure is described.

At S1, the remote controller 10 sends out a corresponding control signalwhen the left body 110 and the right body 120 are pulled apart to atrigger position.

In some embodiments, sliding positions that the left docking portion 111of the left body 110 and the right docking portion 121 of the right body120 of the remote controller 10 slide relatively may comprise aplurality of trigger positions. Different trigger positions maycorrespond to different control signals.

For example, the plurality of trigger positions may respectively be afirst trigger position, a second trigger position, a third triggerposition, and a fourth trigger position that are arranged sequentially.Intervals between ends of the left body 110 and the right body 120 thatare distal from each other may be increased sequentially when changingfrom the first trigger position to the fourth trigger position. Thesensor 200 may send out different trigger signals at the first triggerposition, the second trigger position, the third trigger position, andthe four trigger position, and then the controller 300 may send outdifferent control signals according to the different trigger signals.

At S2, the UAV receives the control signal and performs a correspondingaction.

In some embodiments, the UAV may perform a corresponding action afterreceiving the control signal sent out by the remote controller 10. Thecorresponding action may comprise at least one of the followings:extension-retraction of an undercarriage, deformation of a wing,automatic return, or automatic take-off.

For example, when the left body 110 and the right body 120 of the remotecontroller 10 slide to the first trigger position, the remote controller10 may send out a control signal for stretching the wing. The UAV mayperform an action of stretching the wing immediately after receiving thecontrol signal for stretching the wing.

When the left body 110 and the right body 120 of the remote controller10 slide to the second trigger position, the remote controller 10 maysend out a control signal for automatic take-off. The UAV may perform anaction of automatic take-off immediately after receiving the controlsignal for automatic take-off.

When the left body 110 and the right body 120 of the remote controller10 slide to the third trigger position, the remote controller 10 maysend out a control signal for undercarriage retraction. The UAV mayperform an action of undercarriage retraction immediately afterreceiving the control signal for undercarriage retraction.

When the left body 110 and the right body 120 of the remote controller10 slide to the fourth trigger position, the remote controller 10 maysend out a control signal for automatic return. The UAV may perform anaction of automatic return immediately after receiving the controlsignal for automatic return.

The above-described method for controlling a UAV may at least have thefollowing advantages:

(1) The conventional controlling method requires a user to use somefingers to hold the remote controller 10, while using other fingers tooperate operation buttons or joysticks. On the other hand, according tothe above-described method for controlling the UAV, a control signal maybe generated by pulling the left body 110 and the right body 120 of theremote controller 10 apart. Thus, the user, when holding the left body110 and the right body 120 of the remote controller 10, may only need topull the left body 110 and the right body 120 apart, and thus thedifficulty of controlling the UAV may be significantly decreased.

(2) According to the above-described method for controlling the UAV, aplurality of different control signals may be generated by sliding theleft body 110 and the right body 120 of the remote controller 10 todifferent sliding positions, to implement different functional controlsof the remote controller 10 for an aircraft, thereby further improvingan operation convenience of the UAV.
